Hi, I have a 2019 a200d sport fitted with the hankook tyres, I'm just after some advise as per the road noise inside the car. To me it seems quite noisey and quite obtusive at speeds over 50 mph, on a motorway it's really quite loud with a distinct tyre roar. Is this normal? I've never had an a class before, but my mondeo I had previously was far quieter than this!

In my opinion, the Hankook tires are somewhat louder then my previous Pirelli tires.
So I guess its 'normal'?
Haven't compared the db of the Pirelli and the Hankook so I can't confirm it.

I've got 19" Michelins on my A35, and even with adaptive suspension set to comfort, the road noise on a dual carriageway or motorway is loud. I think possibly it's a trait of the W177...?

I have a A250 with Hankook and have the same problem. If you are doing 70mph on a motorway with a rough surface you cannot have a telephone conversation. It has been back to the dealer 3 times to check the door seals and they say they are good. I have measured the noise level and the peak reading was 106.6 dB. My next step is to complain to the leasing company as the car belongs to them and I did not go down the MB route to get a car that has noise levels way in excess of my wife's Polo.

I think summer tires on this car, in general, are very loud. I replaced my Hankook with Goodyear F1's to try to reduce the road noise, but it only increased the noise, which is weird because the GY are reviewed as rather quiet. With that said, when my EVO 2 Hankook winter tires were on the car during winter I did not notice road noise, at least not enough for me to care, but remember winter tires are 16's and summer tires are 18's! 60's vs 45's. Also, summer tires are harder. If anyone finds a good set of summer tires that are not this loud, please let us know!

However, I do find the wind noise terrible for a premium car!

run flat tyres ?
get rid asap unless you have an a35/45 speedster,its just snobbery when it comes to branded tyres,i learned a long time ago how noisey the w176 is,so for 3 yrs ive run a cheap budget tyre called lansail non run flat,they last for ages and transforms the noise,check it for yourself,you car will be transformed when you get the **** run flats off,just my opinion

Funny you should say that about initial drives and wearing in. I swear the road noise is quietening down in my car, or maybe I’m just getting used to it. The A35 is not a quiet car, but then I didn’t expect it to be...

I have the Hankook ventus EVO S1 (?2) MOE run flat 225/45 18" tyres (all Australian A class are flat). Mine is the A 200, torsion beam.

I have done 4,500 Km now. The car is quiet on smooth bitumen. On coarse road surface, you can hear certainly hear the tyre noise. It is not too bad. On really coarse surface it can be quite noisy.

Interestingly, the car section of a major Aust newspaper reviewed the new Mazda 3 against the new Golf Highline TSI and recorded 60 Db at 100 km/hr (about 62 mph) for both cars.

Can you get an App for an android phone to measure Db?

Hi everyone, I've purchased an A200d premium and I'm very happy with it.

I've just noticed that the road noise, or tyres noise, can be very loud in some asphalts. It's something I just can't get used to that, I think, because I've made 6000 Km with my car and I still can't stand that!

I've read other threads about this problem, but no one suggested a solution.

I was wondering if changing the tyres size, maybe with a 17" rim, could reduce the noise. Now I've 18" mounted

Thanks

Hello to all,

I've got a A200d premium and I'm very happy with it. The only problem I have is the road noise, that can be really high when I drive in rough asphalt; I mean sometimes is hard to understand a telephon conversation.

I've seen other users complain about that, but no one talking about a solution to this problem.

I've got 18" wheel rims, maybe switching to 17" could lower the loudness?

The a class unfortunately is not one of the quitest cars but you can do something.

1) lower tyre pressure. Even a small decrease might help reduce road noise inside.
2) if you can, switch to higher profile tires (which to some means uglier car :)), 205/55R17 or even 60R16, but you might have to change the rims also
3) choose the tyre brand based on the noise levels (if you have comparison data available). There are differences. Bullet proof silent tire is Michelin CrossClimate. Bridgestone turanza is one of the noiser ones. Note that the outside noise a tyre produces is different from the cabin noise.
4) do not choose the highest speed rating. S or T is ok.
